4GHz Wireless Testing RF Matrix Switch: NEXUS-4

The NEXUS-4 is a bi-directional fully non-blocking 32x32 RF matrix switching system that can route any input ports to any outputs in a 6 RU chassis. With the frequency range of 700 MHz to 4 GHz and the capability of expanding to 256x256, it enables large scale wireless testing that involves many MIMO base stations and devices. The built-in programmable attenuators and efficient automation interface provide ease-of-use testing of signal fade and emulation of mobility scenarios. It can dramatically increase lab efficiency by eliminating manual patch panel and cabling as it can be remotely reconfigured for different test setups consistently in seconds. The utilization of the NEXUS-4 will expand your testing capabilities, improve ROI of lab instruments, and reduce time to market.
